All part numbers provide 25% tolerance on inductance
Custom designs are available to meet your specific requirements; please contact factory
*Add “LF” suffix for RoHS requirement. Example: SMT45A-220LF
Gowanda designates a component RoHS-compliant by adding “LF” (lead free) to the part number.
These LF components meet the ≤ .1% lead requirement and they are compatible with 260°C soldering processes.

• Operating Temperature Range:
-55°C to +125°C
• Current Rating is based on a 40°C temperature
rise at an ambient temperature of 85°C
• Saturation Current is the approximate value that
will reduce the initial inductance by 30%
